a citizen of the' United States, and a resi-- dent of the city of New'Yo rk borough of the Bronx, inzthe' county of Bronx' and State of NewYork, have invented anew.

the following is a scription. T p

This invention relates to, automobile locks and has forian obj ect toprovide an improved full, clear, and exact Zdeconstruction for solooking the automobile as to'prevent theft to a largeextent .while beingcapable of complying with the usual laws now in force in?difierentstates'.

Another object of the invention is to provide a theft-lock forautomobiles which will holdthe controlpedals in an inoperative position.i

A still further object is to provide theft,"

lock ior' automobiles'which may be moved to an operated position by thefoot and act to hold the clutch out and the brake in.

Referring to the accompanyingdrawing by numerals, 1 indicatestheflooringofan automobile and '2ethe dashboard. The automobile is provided. withthe; usual steering post 3 and with the usualpedals-t and 5 forcontrolling the clutch andjthe brake. lVhen thesepedals are pushedforwardly or down, the bra:keisapplied and the clutch; is thrown out.This construotionispld and well known and forms nojpalrto f the p res-re-nt invention. However, these parts ool-actwith the lock shown inFigure through the action of the arms6 and 7 which arms are adapted tobe moyed downwardly by the foot against the pedals rand '5 and thendownwardly with; theipedalsv until their e23 treme setposition-is'attained.

When arm 6 is arrangedas shown in,

Figure 1 or in case both arms are in' a locked position and it isdesired" to unlock the same, key 8 is inserted into lock and rotated ina proper direction for causing the block 25 to move toward the lock 30.The movement of this block is sufiicient to pull on the link 23 and lugor ear 20 so as to raise the pawls'16 and 16' out of engagement withtheir respective ratchet wheels 13. As soon as the'pawls have beendisengaged from the ratchetwheels, the sprlngs 14 will quickly throw thearms back to an' inoperative position as indicated in respectto arm lyto a locked position or both arms may-be moved'simultaneously to alocked position.

In applying the'brake, thebrake pedal does not always move in the sameposition and, consequently, one fixed position would What I claim is:. r

' 1. A theft, lock for automobiles comprisnot be sufiicient to properlylock the brake in a braking position. The provision of the ratchet wheel13 and pawls takes care of this contingency and permits the brakepedalto be pushed down as far as desired. The pawl 16 will merely slip overthe ratchet wheel until the ratchet wheel finaly comes to a rest. Inorder to insure proper engagement of -the pawls with the ratchet wheels,the

spring 31 is provided for each of the pawls 1'6 and 16,

As shown in Figure 1, asuitable'encircling clamping structure 32 is provided which ispreferably riveted so that it will not become dislodged accidentally norwill it permit easy removal by an unauthorized person.
